Even in this case, the amount of exhaust heat from the internal combustion engine 1 increases and the amount of heat used increases, so there is no shortage of heat that can be used for multiple purposes, and the internal combustion engine 1
Since the temperature of the returned circulating water can be kept relatively low, by operating the heating section 8, the water can be used at a desired usage temperature at all times. The heating section 8 may have any configuration as long as it can heat the circulating water. For example, it detects the temperature of the circulating water on the downstream side (or upstream side in some cases) and adjusts the temperature to the set temperature. It is possible to configure a configuration that controls the output so that the following happens.
